Unity Multiplayer "Failed to read the ID for the match maker"

Hello,

I have followed the steps in the documents to set up a project that can use the multiplayer service. I have pasted my Cloud Project ID into the corresponding field in PlayerSettings. In my scene I am using the NetworkLobbyManager and NetworkManagerHUD components. When I run the game in the editor and click the button labeled "Enable Match Maker (M)", the following message is outputted to the console.

Failed to read the ID for the match maker, please set the Cloud Project ID string in the Player Settings (see https://unet.cloud.unity3d.com).
UnityEngine.Networking.NetworkManagerHUD:OnGUI()

But the ID is already provided. I don't know what is wrong.

 

I get the message too, And I don't know what to do next.

 

you want to call this before trying to connect:

Code (CSharp):

1. PlayerPrefs.SetString("CloudNetworkingId", cloudId);

where cloudId is your UNET ID, not the Cloud Project ID.
